Spinal Fusion
The medical term for “fusion” is arthrodesis, which refers to the bony fusion of two bones which previously formed a movable joint
The “fusion” is only acheived when there is bony union of the bone
The metal/titanium rods & screws are only meant to hold the bones in place to allow for bony growth, union, and fusion. You can think of them as a “cast” and once placed, they are not typically removed after fusion has occured.
